The connection of brain and hand 手與腦的連結
In the event I held last month, I helped a mother to check her child personality by fingerprints. Once she listened to the result, she said "That was amazing! How could know that? " I replied her with little explanation. After that, she asked "How old can the children be determined by dermatoglyphics? " "15 weeks after the embryo fertilized." I replied with humor. She was shocked.
上個月的一個活動中，我幫助母親通過大腦皮紋檢測分析她的孩子的個性。聽到結果後，她說：“真是太勵害了，你是怎麼知道的？”我解釋了一些背後理論給她了解。之後，她又問“孩子多大才可以做大腦皮紋分析？”我幽默地回答：“成胎後15週後”。她很立即感到非常震驚。
Why does dermatoglyphics help to determine such as deep inside a person? This was about the fetal development in the womb. There are germ layers , endoderm, ectoderm, and mesoderm, within an embryo. Both skin cells and nerve cells developed in ectoderm. Some nerve cells, therefore, attack the skin cells in our hands and feet. That is the reason why we have fingerprints and feetprint. The nerve cells attacked the skin cells has connected with the brain, so that they could left the patten of the brain our fingers. The process finishes in the 15 weeks of the fetal development.
為什麼大腦皮紋分析有助於確定一個人的內心深處？這是關乎胎兒在母體發育的階段。在胚胎內有三個不同的胚層：內胚層，外胚層和中胚層,而皮膚細胞和神經細胞同樣在外胚層發育。因此，一些神經細胞會攻擊我們手腳中的皮膚細胞。這就是為什麼我們有指紋和腳紋的原因。當大腦發展完成時,神經細胞亦會同時侵襲皮膚細胞，使我們的手指留下大腦的印記。以上過程在胎兒發育的15週內完成。
The cerebral cortex (brain) is generally classified into five lobes: the pre- frontal and frontal lobes, parietal lobes, temporal lobes, and occipital lobes.
Prefrontal lobes: intricated cognitive reaction, personal characteristic representation, decision making, and social reaction.
Frontal lobes: Organization,concept thinking, problem solution , judgment and attention
Parietal lobes: Sense of touch, body movements and manipulation of objects
Tamporal lobes: Auditory ,speech, and language
Occipital lobes: visual stimulation, determination of color, and vision involvement .
大腦皮層被通分為五個葉：前額葉和額葉，頂葉，顳葉和枕葉。
前額葉：複雜的認知反應，自我認知及個人特徵，決策和人際關係。
額葉：組織，概念思維，問題解決，判斷和關注
頂葉：感覺，身體動作和技體操縱
顳葉：聽覺，言語和語言
枕葉：視覺刺激，顏色決定和視力。
The correspondence with finger :
Pre-frontal Lobe: thumb
Frontal lobes: index finger
Parietal lobes: middle finger
Tamporal lobe: ring finger
Occipital lobe: little finger
與手指的對應：
前額葉：拇指
額葉：食指
頂葉：中指
顳葉：無名指
枕葉：小指
